To all whom fit may concern:

Be it known. that we, GEORGE W.y BIRD, and

HoYT AKiNs, citizens of the United States,

.residing at'Statesboro, inthe county of Bnl- 5 loch, Stateof Georgia, haveinvented certain new and useful Improvements in Force-Feed \`Lubricato rs; andwe doI hereby declare the.

following .to be a full,clea'r, and exact de-r scription of the inventioingsuch as will -en-A able others skilled in the. art-.to which it ap;-

pertainS toinake and use .the-samejr f This invention has relation to that kindof lubricators or oilers that comprise a cup: that -isadaptedto be attached to, thecap or` covering of the journal-bearing through theme-` clium ot'a stern st :rew'ed therein, through which stem the lubricant is f ed by'force to the journal ors'pin'dle and its bearing as requirech It is the object of' the inventionto provide iinprovements in the class..v of devices nienvtione'd that will-simplify their construction,

reduce the cost of their manufacture', and

enhance their efliciency'fin certain connections and render theniready of use and' certain in their'operation.

The nature of the invention is-fully and. clearly ascertained'. from the device portrayed inthe annexed:` drawing, forming a l .part ot'V this specificatiomfin view of which itY will f irst bedescribed with respect toits con.- struction and modeof operation, and thenbe pointed out in the subjoined claims.
